Key to any NFL franchise move to Los Angeles remains a stadium. No one is interested in seeing a team return to the venerable Coliseum, and venue issues have been and continue to be the death knell of franchise desires in the nation's second-biggest TV market.

"We know there are millions of fans who want a team there," commissioner Roger Goodell has said. "We would love to do that, but it has to be successful."

Success equals stadium.

That hasn't stopped the panic in St. Louis, where the Rams moved and could soon vacate. The problem: You guessed it, the stadium.

The Rams' home is the Edward Jones Dome, which was under construction in St. Louis when the Rams fled L.A. It is neither antiquated nor inadequate. It just isn't fabulously luxurious.

The team and stadium management are haggling over throwing money around for an upgrade while whiffs of abandonment emanate from the building. According to the St. Louis Post-Dispatch:

The Rams will be in the same situation next year at this time if the team and St. Louis fail to reach an agreement on fulfilling "first-tier" stadium lease provisions. Fourteen months ago, arbitrators ruled in favor of a Rams' proposal calling for an estimated $700 million in stadium improvements at the Edward Jones Dome — not much less than a new stadium would cost.

While St. Louis sweats, other teams are making their fans worry. Given their sojourn in L.A., the Raiders seem a prime candidate.

The Raiders abandoned L.A. shortly after the Rams, returning to their roots in Oakland. Therein lies the problem. They play in O.co Coliseum, a stadium grungy enough to match the team's image in its heyday. But with the San Francisco 49ers getting a fancy new playpen, the Raiders too want to upgrade accommodations.

Raiders owner Mark Davis tried to pooh-pooh notions of his team casting loving glances at Los Angeles, the Post noted. But he also admitted he has thought about following Papa Al's lead into the City of Angels.

With Ralph Wilson's death, questions are being raised about the Buffalo Bills' future. And with L.A. the flavor of the month it's not hard to imagine Wilson's successors fleeing Buffalo's nasty winters for sunny Southern California.

The Bills could be sold, which puts even more uncertainty in its future. And guess what could be a deciding factor? Yep, a new stadium. One either in Buffalo or closer to Toronto that could tap into Canada's largest market. A dome would be welcome.

A change of ownership a few years away, according to The Buffalo News. It also noted the team's current stadium lease runs though 2023 and has a severe buyout restriction. Except ...

There is an out clause in the lease that would allow the team a one-time option, in 2020, to buy out the final three years of the deal for a payment of only $28.4 million.

As for the Rams, owner Stan Kroenke is a Missourian and second-richest NFL franchise holder, thanks to his success as a retail center developer and marriage into the Walmart fortune. Kroenke is noncommittal about the team's future.

And by the way, if the league really wants to be adventurous, why not let a team move to London? Of course, there's one big need before that happens.

You guessed it, a stadium. And guess who owns an English soccer team? Stan Kroenke.
